Thanks Nancy. Yes, It was an issue with the filename.
Need your assistance in another issue. Is there a mechanism in FrameMaker to define short file names for HTML files. Due to some character restrcition, builds are failing. How to restrict the file path/name length in FrameMaker as the file names are generated automatically by FrameMaker?
For example, PPS_Admin_Guide%2FPPS_L2Enforcement%2FPPS_Policy_Enforcement_SNMP_SSH%2FACL_Configuration_for_Default_Restricted_and_Full_Access_RoleRestricted_ACL_give_access_to_DHCP_se.htm
